Colored Romex:

As most DIYers have started to see, there are now colored cables to choose from. Many manufactures have started producing
White - 14ga
Yellow - 12ga
Orange - 10ga
At this time there is no standard, but might not last long. Also there are no Code requirements for what color or use.
The best reason for this colored cable seems to be an easy way for inspectors to identify the color with the gauge.
If any one has found this colored cable Beneficial fill free to chime in.

How about this:
Blue Romex: 14/2 with a blue/yellow instead of a white/black
(to simplify switch loops)?
tan sheathing, 14/3with Blue/Yellow/tan inside.

There is in Canada , Red romex, which signifies red/black
conductors. commonly available in 12/2, but I have seen some
8/2 in places. The 12/2 is used for fixed 220V heaters, including
water heaters. I have seen it used as switch loop wires as well.

In the olden days, there used to be orange, brown, blue, black, as well as white sheathed NM-B cable, with no rhyme nor reason to the coloring.

Heck I have two pieces of I dentical romex, both regular 12/2,
both made in the same place, the only differnece one is brown, the other white. (they run together to run two separate fixed
appliances, I guess different colours were installed to differentiate the two)

I find it amazing that in a world that can produce a machine screw to the same thread specifications anywhere, such a heavily code governed item as wire sheathing is not standard.

I think you will see it become a standard, and possible in the NEC.
I'm not sure how the inspectors fill about it, maybe one will give his opinion.
I fill it would help diyer’s to know what color is what awg, or what color can be used for what. I get a usual comment about a person needing 240volt wire a lot. Sometimes It can be fun to tell them “All I put in is 600volt wire.
